Led mag lockout?

[Deftoner]

I read the other day that having just a led can cause a mag lockout? My last grow(1st with led) went terribly wrong. No matter how much mag i feed her she still kept spotting and drying up. Has anybody ran into this problem with led?

Sounds ridiculous to me.

The newbie's post echoes the only thing I was thinking: the reduced radiant heat from LEDs is causing your medium to be too saturated.

Runoff 2200ppm is the problem. Must be a lockout.
I see tip curl, deformed leaves and the cal rust spots.
Were you feeding Lucas every watering at 700-800?
Im thinking with your soil mix and nutes you would either want to water 1/3 strength every watering, or full strength every few waterings. But it looks like you need to flush and feed lightly until the plant snaps out of this...
Maybe raising the light wouldnt be a bad idea until they arent so stressed.

I got rid of the jungle juice and have invested in general organics full lineup. Ya I was feeding 1/4 strength every watering.
